TABLE.

Specication of Letters Patent.

Patented May 9, 1916..

Application filed August 16, 1915. Serial N o. 45,774.

To all wh-0m t may concern:

Be it lrnown that we,Josm H SrosiNsnr and HENRY KUBIAK, a citizen of theUnited States and a subject of the Czar ot' Russia, respectively, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and uselul improvements in Tables, of which the following is a speciiication. y

Our invention relates to improvements in tables, and more particularly to an improved seltl leveling table in which weighted levers are employed to maintain the table in a horizontal position regardlessof the angle ol the pedestal supporting the table. y

A further object is to provide a table having a central thrust bearing on the pedestal supporting the same v having improved means for causing the table to maintain a horizontal position regardless ofv the position ot' the pedestal, and provide an arrangement of springs yieldingly securing the table on the pedestal, but allowing the same the necessary movements. l y

With these and otherk objects in view, the invention consists in certain novel features of construction and combinations and arrangements ot' partsas will be more fully hereinafter described and pointed out in the claims.

ln the accompanying drawings: Figure 1 is a view in side elevation illustrating `our y improvements, one of theV springs being omitted for purposes of clearness. Fig. 2 is an inverted sectional plan view, the section being taken on the line 2*,2 of Fig. l, and the springs are omitted for purposes of clearness. Fig. 3 is an enlarged detail view `in section on the line 3-3 oli' Fig. 2, and Fig. fl is a similar view. on the line 4 4 ot Fig. 2.

1 represents a pedestal, and 2 the table which is made with a central bearing '3 to receive a conical thrust journal 41: and support the table at its center. The table 2 is provided on its under face with :four eyes r5, and coiled springs 6 connect the eyes 5 with similar eyes 7 on the pedestal 1, thereby elastically holding the table on the pedestal, yet allowing the same a certain amount of movement in order to accommodate itself with the movement of a' ship, and we would have itl understood that the springs are so located that they do not interfere in any way withthe yordinary movements of the Several parts hereinafter described.

Vbrackets S and lthe weighted lends of Metal brackets and 9 are secured to pedestal 1, and 4these lnacketsv support worm shafts 10 at right angles toeach other. The worm shafts are provided on their ends with beveled pinions 11, which mesh with segments 12 having pivotal mounting on the p 9 respectively. Depending levers 13are fixed to move with the segments 12, and'theselevers 13 at their lower ends are provided with weights 111, and the weights compel the levers to maintain a perpendicular regardless of the movement yof the ship, and the movement of the levers imparts rotary movement to the worm shafts asl will be hereinafter described. The levers 13 are made in two parts 13a and 13', connected by hinges 18. These hinges allow they levers to swing' outwardly in one direction, so that when one lever is swinging in its normal path to move the table, the lower end ofV the other lever can swing on its hinge, and relieve any strain upon the segment and its cooperating parts. This is shown in Fig. 1.

On the .shafts` 10,-worms 15 are secured, and mesh ywith worm segments 1G. The segments 16 are liXed to shafts 17, and the latter are supported in bearings 18 on the under face of the table. The shaftsV 17 are rendered suflieiently flexible to compensate. for varying positions of the table by constructing said shafts of two sectionseonnected by universal joints 17u. The outer ends of the yshafts 17 are Xed to rods 19 and the rods 19 operate as double cranks, and are pivotally connected by links 20 with brackets 21 on the table. The arrangement of rods 19 and links 2O permit a' certain amount of ilexibility between the shaft 17 and the table, and

compensate tor various angles which the pedestal may assume. Furthermore, the

ytransmission of motion from the gear seg-V ments to the table is through the medium of the several links 20, and the Vsprings 6 and thrust bearing 3 compel the table to move easily and with a certain amount of cushion in all directions, overcoming sudden jars which would of course be objectionable.

Various slight changes might be made in the general form and arrangement of parts described vwithout departing vention, and hence we do not limitfourselves to the precise details set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims;

from our into the last-mentionedr shafts and meshing with worms on the worm shafts, and means A levers, Y f' estal, pinions on the worm shafts meshing 1. A Vdevice of the character described,

comprising a pedestal, a table-movably supported on .the pedestal, springs connecting the table with the pedestal, pivoted levers Asupported on the pedestal, Vshafts mounted f on the pedestal, means for transmitting a turning movement Vto the shafts when the levers are pivoted, and means operated by the shafts to move thetable at an angle to the pedestal when the l'ever'is moved, substantially asy described. l

2. A device of the character described, comprising a pedestal, a table having 'a thrust bearing on the pedestal, springs connecting the table with the pedestal, pivoted levers supported on the pedestal, segments secured to move with the pivoted ends of the levers, weights .on the lower ends of the levers, worm shafts supported on the ped estal, pinions on the w'orinshafts meshing with the segments, and means operated by the worm shaft for moving t-he table, sub* stantially as described.v

BfA device of thel character described, comprising a pedestal, a table having a thrust bearing on the pedestal, springs connecting the table with the pedestal, pivoted levers supported on the pedestal, segments secured to move with the pivoted ends of the levers, weights on the lower ends -of the worm shafts supported on the pedwith the segments, shafts supported on the bottom ofthe table, worm segments secured Uopos of this patent may be obtained for bottom of the table, worin segments secured` tothe last-mentioned shafts and meshing with worms on the worin shafts, rods se-V cured between their endsv to said last-mentioned shafts, and links pivotallyv connecting the ends of said rodsk with the bottom of the table, substantially as described.

5. AV deviceV of the character described,

comprising a pedestal, a table having a thrust bearing on the pedestal, springs connecting the table with the pedestal, levers pivotally supported at their upper ends ,on the pedestal, said levers comprising two members hinged to swing in one direction only and having'weights at their lower ends,

and means operated by the levers for moving the table at an angle` to tie pedestal,

substantially as described.

In testimony whereof we naines to this specification in the presence of twoV subscribing witnesses. Y
